What should I do if the gear of the high frequency quenching machine is deformed?

The influence of cold working of high frequency quenching machine on the deformation of carburized gears, due to the hot tooth shape and tooth surface direction, tooth shape and tooth surface direction, the influence of cold working on the tooth profile and tooth deformation of carburized gears has not been dealt with, and the deformation will be reduced The precision of the gears, thereby reducing the smoothness of motion and increasing the noise of the machine.

The deformation law of tooth shape and tooth direction of high frequency quenching machine gear, low carbon alloy structural steel gear, the tooth shape and pressure angle increase, the tooth tip becomes negative, the helix angle of the helical gear decreases in the tooth direction (tooth straightening) , In the actual production of the high-frequency quenching machine factory, there are many reasons for not complying with the above regulations.

The influence of cold and hot processing on gear deformation, although the heat treatment workers of high frequency quenching machine do a lot of work to prevent and reduce the deformation of gears, as said at the beginning, deformation is inevitable, and it is unrealistic to completely avoid deformation, so that It is very difficult to rely on heat treatment to solve the precision requirements of gears.

However, the induction hardening machine can explore the deformation law of heat treatment through production practice, and try to stabilize the deformation. The heat treatment gear can meet the technical requirements through hot and cold processing, reasonable tolerance distribution or changing the coordination of the position of the tolerance zone.
